BRAKE CONSTRUCTION Application led September T0 all ttt/10m, it 11mg/ concern.'

Be it known that I, JOHN IVILLIAM Nolens, a citizen ot the United States, and a resident oit Kimball, in the county ot Kimball and State ot' Nebraska, have invented a new and uset'ul Improvement in Brake Constructions for Motor Vehicles, ot which the following is a full, clear, and exact description,

lily invention relates to improvements in brake Constructions for motor vehicles, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object ot my invention is to provide a brake construction for motor vehicles ot that. type in which the brake band is applied to one part ot the planetary transmission when the toot brake. is actuated, this brake construction consisting` ot novel means for connecting the emergency lever et the vehicle with the brake pedal, whereby the brake band ot the planetary transmission will be actuated when the emergency lever' is actuated, thus making it unnecessary to provide a brake band on the rear wheels oit the vehicle.

A further object ot my invention is to provide a device of the character described which is if'ery simple in construction and which may be readily attached to the vehicle with but slight alterations being necessary in the latter.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, 'forming part oit this application, in which Figure 1 is a perspective view of an engine which employs the planetary transmission, showing my device operatively applied thereto,

Figure 2 is a side elevation or' the device,

Figure 3 is a section along the line 3-3 ot Figure 2, and

Figure 4 is a section along' the line 4 4 ot Figure 2.

In carrying` out my invention, I make use ot an engine, indicated generally at 1 which is provided with the usual brake pedal 2, clutch pedal 3, and reverse pedal 4. In Figure 1 I have also shown a rod 5 to which the emergency lever 6 is secured. The

emergency lever is normally connected by a meansV (not shown) with the brake band on the rear wheels of the car. A speed lever 7 is also secured to the rod 5 and is adapted to actuate the clutch lever 8 so as to throw the engine in neutral when the emergency lever is actuated. The parts heretofore described arc ordinary in construction and torni no part ot my invention except in so tar as they cooperate with the parts about to be described.

In the present form of the device I have discarded the brake on the rear wheels and the connections between the emergency lever and the brake. In the present form of the device they emergency lever 6 is connected to the brake pedal 2 by means of a rod 9 (see Figure 2). A casting 10 is secured to the brake pedal 2 by means ot a U-bolt 11. The speed lever 7 also has a casting 12 secured thereto by a U-bolt 13. rllhe rod 9 is threaded into a yoke 16 which in turn is pivotally secured to the casting 10 at 14. The other end of the rod 9 is slidably received within a slot 15 in the casting 12. The rod 9 is adapted to be lengthened or shortened by merely turing the rod in the yoke 16. The lock nut 17 secures the rod in adjusted position. The lock nut 17 also holds one end of a spring 18 to the rod 9, the other end of the spring being secured to the U- bolt 11 by means of one of the nuts 19 of the bolt.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. In operation, it is customary to use the brake pedal 2 when slowing up the car and to use the emergency lever 6 when bringing the car to an abrupt stop. I have found that by connecting the lever 6 With the brake pedal 2, the emergency brake band can be done away With. In this manner the brake band in thev planetary transmission is actuated when the brake pedal 2 is moved orv the lever 6 is moved.

The brake pedal 2 can be used in the ordinary manner, since it will be noted that When the pedal actuated, the rod 9 mercly slides Within the slot 15 and does not actuate the speed lever 7. The spring 1S yielding'ly holds the rod 9 against the upper side of the slot 15 so as to preventrattling of the rod while the car is in n'iotion.

IVhen it is desired to stop the car, and

at the saine same time to throw theengine into neutral position, the lever 6 can be actuated in the ordinary manner. The lever instead of tightening the brake band about the rear Wheels of the car, Will swing the speed lever 7 so as to cause the clutch lever to thrown the clutch pedal into neutral position and to swing,` the casting lvso as to move the rod 9 and the brake pedal 2, the movement of' the brake pedal applying` the brake in the planetary transmission. The car functions in exactly the same manner as When the device is not applied thereto, except that the brake band in the planetary transmission is actuated each time the brake edal 2 or the emergency lever G is act-u-v ated. lt will therefore he apparent that l have eliminated the emergency brake hand from the rear Wheels and the connections thereto and instead employ but one brake band for both the pedal and the lever. The device is positive in operation and can loe readily applied to any car in Which the planetary transmission is employed.

I claim:

The combination With an automobile having` a brake pedal, a sha-ft, an emergency lever secured to said shaft, and a speed lever secured to said sha-ft, of an arm havingI a slot therein and rigidly secured to said speed lever, a link operatively connected to said brake pedal and having its free end slidahly disposed in said slot, said link having, a head adapted to engage with said arm when said emergency lever is actuated, and spring` means for holdingv said link against the top of said slot.
